Craspedia plant named ‘DCRAGOLFBY’

ABSTRACT

A new and distinct  Craspedia  cultivar named ‘DCRAGOLFBY’ is disclosed, characterized by early flowering and a higher than average amount of flowering stems per plant. Plants can tolerate high temperatures to 35 degrees C. The new variety is a  Craspedia , normally produced as an outdoor garden or container plant.

Latin name of the genus and species: Craspedia globosa.

Variety denomination: ‘DCRAGOLFBY’.

BACKGROUND OF THE INVENTION

The new Craspedia cultivar is a product of a planned breeding program conducted by the inventor, Gavriel Danziger in Nir-Zvi, Israel. The self-pollination resulting in this new variety was made during March of 2012.

The parent is the unpatented, propriety variety referred to as Craspedia ‘CR.12-165’. The new variety was selected in March 2013 by the inventor in a group of seedlings resulting from the 2012 self-pollination, in a greenhouse in Nir-Zvi, Israel.

Asexual reproduction of the new cultivar ‘DCRAGOLFBY’ was first performed by vegetative cuttings during December of 2009, at a greenhouse in Nir-Zvi, Israel. Subsequent propagation by vegetative cuttings has shown that the unique features of this cultivar are stable and reproduced true to type in multiple successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘DCRAGOLFBY’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘DCRAGOLFBY’ These

-   -   1. Early flowering.     -   2. Increased quantity of flowering per plant.     -   3. Very good heat tolerance.

PARENT COMPARISON

Plants of the new cultivar ‘DCRAGOLFBY’ are similar to plants of the parent in most horticultural characteristics, however, plants of the new cultivar ‘DCRAGOLFBY’ differ in the following;

-   -   1. The new variety begins flowering approximately 3 weeks before         the parent variety.     -   2. The parent variety produces on average 6 flowering stems, the         new variety produces on average 10 flowering stems.     -   3. The new variety tolerates temperatures up to 30 to 35° C.,         the parent variety cannot tolerate temperatures this high.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘DCRAGOLFBY’ can be compared to the unpatented commercial variety Craspedia ‘DPBALGLOBE’. These varieties are similar in most horticultural characteristics however, ‘DCRAGOLFBY’ differs in the following:

-   -   1. ‘DPBALGLOBE’ has larger flowers than the new variety.     -   2. ‘DPBALGLOBE’ flowers approximately 2 to 4 weeks later than         the new variety.     -   3. ‘DPBALGLOBE’ produces longer foliage than the new variety.     -   4. Plants of ‘DPBALGLOBE’ are taller than plants of the new         variety.

Plants of the new cultivar ‘DCRAGOLFBY’ can also be compared to the unpatented commercial variety Craspedia ‘DPBALPOP’. These varieties are similar in most horticultural characteristics; however, ‘DCRAGOLFBY’ differs in the following:

-   -   1. ‘DPBALPOP’ produces on average 13 flowering stems per plant,         whereas new variety produces on average 10 flowering stems per         plant.     -   2. ‘DPBALPOP’ is taller than the new variety.     -   3. ‘DPBALPOP’ flowers 3 to 5 weeks later than the new variety.     -   4. Flower diameter of ‘DPBALPOP’ is larger than the flower         diameter of the new variety.     -   5. ‘DPBALPOP’ has a flat flower head shape while ‘DCRAGOLFBY’         has a round flower head shape

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘DCRAGOLFBY’ grown in 25 cm pots outdoors in Nir-Zvi, Israel.

FIG. 2 illustrates in full color a close up view of a typical inflorescence of ‘DCRAGOLFBY’. Age of the plant photographed is approximately 11 weeks from a rooted cutting.

The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
